What were some ideas martin Luther wanted to debate?

Martin Luther sought to debate several key ideas, primarily the sale of indulgences, which he viewed as a corrupt practice undermining true repentance and faith. He argued for justification by faith alone, emphasizing that salvation is a gift from God rather than something earned through works. Additionally, Luther challenged the authority of the Pope and the Church, advocating for the Scripture's primacy over ecclesiastical tradition. His theses sparked a broader discussion on reforming the Church and returning to biblical foundations.
